# Lecture/Presentation

• ### Computer Animated Statistics

This site offers a collection of applets in which standard topics of statistics and probability are presented in a novel and visual way using computer animated images. Topics include dependence, independence, conditional probabilities, expectation and variance, normal, exponential, Poisson distributions, law of large numbers and the central limit theorem, hypothesis testing maximum likelihood estimation, sampling, chi-square tests, and the construction of confidence intervals.
• ### What Are The Odds?

This website provides lesson plans, activities, a problem bank, and links to references that meet NCTM standards for probability.
• ### Poisson Sampling Distribution Generator (with Specific Mean)

This page generates a histogram of a Poisson distribution and the associated table of probabilities. Upon opening the page, users will be prompted to enter the mean of the distribution (between 0.01 and 20.0, inclusive). Key Word: Poisson Calculator.

• ### Strategies for data analysis

This presentation on data analysis addresses observational studies and randomized controlled trials in two different sections. Types of studies are defined and examples of each study is given to emphasize the differences. Factors and variables are also discussed.

• ### Z-test for difference between means

A slideshow presentation with two good examples on using the Z-test for the difference between two means. Gives some good "plain language" interepretations of what "statistically significant difference" means.
• ### Two Sample Hypothesis Tests for Proportions

Gives some examples of two sample proportions. Shows how to answer using formulas and minitab.
